IF YOU TRY PRINT THIS ON CARDSTOCK, YOU'RE GONNA HAVE A BAD TIME

You'll need an X-acto knife.

For mobs: Shrink the mobs, cut/glue them, and then put it inside the spawner.

ALSO: DO NOT CUT THE WHITE OUT FIRST! GLUE IT TOGETHER THEN CUT IT!

Edit: I do realize that some people don't have bigger printers for this. I am working on a fix for this.

UPDATE: Fixed. It should print at the correct size now.
